Systems and methods for operating system migration
The present invention provides for systems and methods that recognize source and target devices and automatically identify, transfer, and convert user profiles, user settings, data, applications, and other information from the source device with its source operating system to the target device with its target operating system. The system surveys both the source device and the target device to ensure that each device has the appropriate resources and configuration to support the migration. Objects to be migrated are then identified, transferred to the target system and converted as necessary to create a similar environment on the target device as the previous environment on the source device. The post transfer integrity of the target device is then analyzed to ensure that the target system continues to work for its intended purpose and to further ensure that the migrated environment is also operational on the target device.
The present application claims priority to U.S. provisional patent application Ser. No. 60/592,077 filed on Jul. 28, 2004, which is incorporated herein by reference in its entirety.
BACKGROUND1. Field of the Invention
The present invention generally relates to the field of data migration and more particularly relates to migrating and converting data, settings, user profiles, applications, and other information from one operating system to another.
2. Related Art
When a computing device user wishes to change from one operating system to another or from one device to another, the user is faced with the difficult task of migrating all of the information that the user has accumulated on the device. In many cases, this information may be stored in memory and/or on storage peripherals in various locations that the user may not even be able to find. Moreover, the documentation needed to locate all of a user's information is scarce and highly technical. Furthermore, few vendors offer products to aid in migration tasks.
These significant problems are exacerbated by the large number of open and proprietary data formats that exist between applications, devices and operating systems. Often a complicated file conversion is required to move data from one system to another and few products and little documentation are available to assist the user in this arduous task.
Therefore, what is needed is a system and method that overcomes these significant problems found in the conventional systems as described above.
SUMMARYAccordingly, described herein are systems and methods that recognize source and target devices and automatically identify user profiles, user settings, data, applications, and other information objects on the source device with its source operating system and transfer those objects to the target device with its target operating system where they are converted as necessary for proper functioning on the target device.
In operation, the system may employ executable modules that run separately on the source and target devices. Alternatively, or in combination, the system may employ a server device that conducts the migration method over a network. Furthermore, the data transfer may be carried out on physical media such as a compact disc or it may be streamed or otherwise transferred over a network medium.
The system surveys both the source device and the target device to ensure that each device has the appropriate resources and configuration to support the migration. Objects to be migrated are then identified, transferred to the target system and converted as necessary to create a similar environment on the target device as the previous environment on the source device. The post transfer integrity of the target device is then analyzed to ensure that the target system continues to work for its intended purpose and to further ensure that the migrated environment is also operational on the target device.
BRIEF DESCRIPTION OF THE DRAWINGSThe details of the present invention, both as to its structure and operation, may be gleaned in part by study of the accompanying drawings, in which like reference numerals refer to like parts, and in which:
Certain embodiments as disclosed herein provide for systems and methods that recognize source and target devices and automatically identify user profiles, user settings, data, applications, and other information objects on the source device with its source operating system and transfer those objects to the target device with its target operating system where they are converted as necessary for proper functioning on the target device. For example, one method as disclosed herein allows for a server computer to orchestrate migration of a user account from a source system to a target system where the two systems have disparate operating systems.
After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, although various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set forth in the appended claims.
The devices 20, 30, and 40 can be of any of a variety of computing devices including a personal computer, server computer, workstation computer, laptop, palmtop, personal digital assistant (“PDA”), wireless communication device, cell phone, pager, or any other type of device capable of storing information objects and executing data migration programs. An example wireless communication device and general purpose computer device are later described with respect to
In a practical sense, each of the devices 20, 30, and 40 are capable of running disparate operating systems that control the various functions of each respective device. In particular, the source device 20 and the target device 30 are likely to run different operating systems, for example, source device 20 may run Microsoft Windows while target device 30 may run Mac O/S. Other combinations of operating systems such as Palm OS, AIX, BSD Unix, System V, Sun OS, Solaris, Windows CE, and the like can be running on devices 20 and 30, as will be understood by those having skill in the art.
The data storage areas 22, 32, and 42 can be of any of a variety of data storage devices included integral hard drives, external drives, flash, RAM, ROM, and removable media such as CDROM or DVD. The function of the data storage areas is to house data and programs that can be executed by a processor (not shown).
The input/output devices 24, 34, and 44 can be of any of a variety of devices including portable media devices, network communication interfaces, wireless communication interfaces including IEEE 802.11 interfaces, infra red communication interfaces, Bluetooth communication interfaces and the like. The input/output devices allow each device to gain access to portable media and to provide data on portable media for physical transfer to other devices.
The network 50 can be any of a variety of networks including a wired network, wireless network, public network, private network, packet switched network, circuit switched network, personal area network, local area network, wide area network, or any combination of networks such as the ubiquitous Internet.
In an alternative embodiment, certain modules may be implemented in software or hardware or some combination of the two, such as an application specific integrated circuit. Furthermore, various combinations of modules for the different functional tasks that are carried out by the modules are also possible. For example, in one embodiment there may be just a single module that carries out the functional tasks of all of the modules 100, 110, 120, and 130. In another embodiment there may be eight modules that carry out the functional tasks instead of four modules as illustrated in the embodiment shown in
The object identification module 100 is configured to identify information objects for migration to a target machine. Some examples of information objects include users on the source device (including administrative system users with unique permissions and normal users with standard permissions). Information objects may also include user groups and all of the users associated with such a group. Information objects can also include various data that may be associated with a user account, for example, login scripts, shell scripts, configuration files for various applications such as command line interfaces (e.g., shells), mail programs, browser programs, graphical user interfaces, and the like.
In one embodiment, a group of information objects identified by the object identification module 100 may comprise an “environment” on the source device. For example, a username and password combination, home directory structure, preferences such as login program, configuration files, and the like may comprise an environment that could be described as a specific user environment. Other combinations of information objects may comprise other types of environments.
Advantageously, the object identification module 100 is configured to identify information objects and environments. In one embodiment, the object identification module 100 is configured to automatically identify such information objects and environments. In an alternative embodiment (or in combination) the object identification module 100 can be configured to work interactively with a user or administrator through a user interface that allows the user or administrator to selectively identify information objects and also to selective identify the information objects that comprise an environment.
The object transfer module 110 is configured to transfer identified information objects from the source device to the target device. In one embodiment, the object transfer module 110 may set up a stream of data from the source device to the target device. In an alternative embodiment, the object transfer module 110 may copy the information objects to an interim location such as a server or portable storage medium, and then make a second copy of the information objects to the target device. As will be understood by one having skill in the art, there are many ways to transfer data from the source device to the target device and the object transfer module 110 contemplates each such way to perform this function.
The object conversion module 120 is configured to convert information object from a first data format that is compatible with the operating system of the source device to a second data format that is compatible with the operating system of the target device. The object conversion module 120 is preferably capable of converting various formats of data, including text, ASCII, and binary formats. Similarly, the object conversion module 120 is preferably capable of recognizing interpreted data formats such as HTML, XML, Perl, shell scripts, and other platform independent information objects (assuming the target platform has an interpreter for the specific type of information object).
The migration integrity module 130 is configured to perform both pre-migration and post-migration analyses to determine if the migration can be carried out and to validate that the migration has been carried out successfully. For example, the migration integrity module 130 may survey the source device or target device prior to any migration to ensure that the device has the appropriate hardware and software resources to successfully migrate information objects. Furthermore, the migration integrity module 130 may make before and after comparisons on the target device to verify that the migration has been successfully and completely carried out and also to verify the absence of unintended results. In one embodiment, the migration integrity module 130 may make a pre-migration backup of data on the target device so that the target device may be restored to its pre-migration state if the migration effort was unsuccessful.
If the source device does not pass the survey, as determined in step 210, then in step 220 the source device can be upgraded. The upgrade of the source device can be automatic, such as downloading and installing an updated module for a particular application, or updating the firmware on an input/output device, downloading and installing an interpreter such as a web browser or it could involve more time consuming and labor intensive upgrades such as installing more memory. Once the upgrade is complete, or if none was required as determined in step 210, then in step 230 a communication log is updated or created if none previously existed.
One advantage to maintaining a communication log is so that subsequent operations of the migration utility are not required to duplicate certain steps that only need to be performed a single time or periodically.
If the target device does not pass the survey, as determined in step 260, then in step 270 the target device can be upgraded. The upgrade of the target device can be automatic, such as downloading and installing additional software, updating the firmware, or even reconfiguring or installing new hardware. Once the upgrade is complete, or if none was required as determined in step 260, then in step 280 a communication log on the target device is updated or created if none previously existed.
Next, on the target device, the transferred objects are converted, as necessary, to a format that is compatible with the operating system of the target device, as shown in step 320. A migration signature can be created next in step 330, where the migration signature comprises a list of pre-migration files on the target system and a list of post-migration files on the target system that can be compared to identify the changes that were made as part of the migration. The backup process identified in this step can be performed at any time prior to overwriting files on the target device as part of the migration so that in the case of an unsuccessful migration, the target system can be returned to its state immediately prior to the migration.
Finally, in order to determine whether the migration was successful or unsuccessful, an integrity check is performed in step 340. The integrity check may carry out a comparison of the post-migration signature to the pre-migration signature to analyze whether all of the information objects associated with the migrated environment are in fact present post-migration. Furthermore, the integrity check may also include the test execution of certain binary or interpreted programs to further validate the success of the migration. The integrity check may also provide a graphical user interface, command line interface, configuration file, or wizard interface to allow a user or administrator to also perform certain comparisons to validate the success of the migration.
In the illustrated embodiment, wireless communication device 450 comprises an antenna 452, a multiplexor 454, a low noise amplifier (“LNA”) 456, a power amplifier (“PA”) 458, a modulation circuit 460, a baseband processor 462, a speaker 464, a microphone 466, a central processing unit (“CPU”) 468, a data storage area 470, and a hardware interface 472. In the wireless communication device 450, radio frequency (“RF”) signals are transmitted and received by antenna 452. Multiplexor 454 acts as a switch, coupling antenna 452 between the transmit and receive signal paths. In the receive path, received RF signals are coupled from a multiplexor 454 to LNA 456. LNA 456 amplifies the received RF signal and couples the amplified signal to a demodulation portion of the modulation circuit 460.
Typically modulation circuit 460 will combine a demodulator and modulator in one integrated circuit (“IC”). The demodulator and modulator can also be separate components. The demodulator strips away the RF carrier signal leaving a base-band receive audio signal, which is sent from the demodulator output to the base-band processor 462.
If the base-band receive audio signal contains audio information, then base-band processor 462 decodes the signal and converts it to an analog signal. Then the signal is amplified and sent to the speaker 464. The base-band processor 462 also receives analog audio signals from the microphone 466. These analog audio signals are converted to digital signals and encoded by the base-band processor 462. The base-band processor 462 also codes the digital signals for transmission and generates a base-band transmit audio signal that is routed to the modulator portion of modulation circuit 460. The modulator mixes the base-band transmit audio signal with an RF carrier signal generating an RF transmit signal that is routed to the power amplifier 458. The power amplifier 458 amplifies the RF transmit signal and routes it to the multiplexor 454 where the signal is switched to the antenna port for transmission by antenna 452.
The baseband processor 462 is also communicatively coupled with the central processing unit 468. The central processing unit 468 has access to a data storage area 470. The central processing unit 468 is preferably configured to execute instructions (i.e., computer programs or software) that can be stored in the data storage area 470. Computer programs can also be received from the baseband processor 462 and stored in the data storage area 470 or executed upon receipt. Such computer programs, when executed, enable the wireless communication device 450 to perform the various functions of the present invention as previously described.
In this description, the term “computer readable medium” is used to refer to any media used to provide executable instructions (e.g., software and computer programs) to the wireless communication device 450 for execution by the central processing unit 468. Examples of these media include the data storage area 470, microphone 466 (via the baseband processor 462), antenna 452 (also via the baseband processor 462), and hardware interface 472. These computer readable mediums are means for providing executable code, programming instructions, and software to the wireless communication device 450. The executable code, programming instructions, and software, when executed by the central processing unit 468, preferably cause the central processing unit 468 to perform the inventive features and functions previously described herein.
The central processing unit is also preferably configured to receive notifications from the hardware interface 472 when new devices are detected by the hardware interface. Hardware interface 472 can be a combination electromechanical detector with controlling software that communicates with the CPU 468 and interacts with new devices.

Also included are any other removable storage units 572 and interfaces 570, which allow software and data to be transferred from the removable storage unit 572 to the computer system 550.
Computer system 550 may also include a communication interface 574. The communication interface 574 allows software and data to be transferred between computer system 550 and external devices (e.g. printers), networks, or information sources.
